01/14/19 UPDATE: LyleSnake made a very useful spreadsheet (Post #15 in this thread) to help us monitor our game progress. Thanks for the extra hand, Lyle!
01/14/19 UPDATE: Added a requirement for the Criminal Career!
01/19/19 UPDATE: Revised some rules to increase difficulty, hehe!
01/28/19 UPDATE: Added the option to create pets in CAS since there wasn't any before making it impossible to build a Pet Shop.

Hi. I'm not good with introductions so I'll get straight to it.

Since I find the rule of tax-paying in BaCC a real hassle than a challenge, and I don't use mods and could only download a few cc's, I decided to remove it and changed some rules to suit my game. I read a lot of BaCC rules (including the original, and variants from Nepheris, Keoni, and Deedee to mention a few) to guide me through this revision process and my rules still follow the structure of creating a town from scratch. However, these rules are career-driven, barely requires population count and mods, doesn't require you to own a business, and most importantly, doesn't require you to pay taxes! At all! So if you're up for it, scroll down!

Warning: This challenge will take a lot of time and effort as it requires you more Sims to play to expand. The progression will be slow but it's rewarding to know you worked very hard for it.

STARTING OUT

The challenge begins once you've chosen a clean empty neighborhood. It may be lush, desert, dirt, concrete or a custom terrain for cc users. You may only decorate your hood with trees, beaches, birds, and rocks. Only until you're connected to all subhoods will all neighborhood decorations be unlocked.

CREATING HOUSEHOLDS

Before playing, you must determine how many households you'll begin with. To do this, you roll a dice. Each number corresponds to the number of households you will make. (1-2: 2, 3-4: 3, 5-6: 4)
Now that you have your number of households, the next thing you must determine is the number of Sims for each household. You will call your first Sims your "settlers". To do this, you must roll the dice for every household you create. (1: 1, 2: 2, 3-4: 3, 5-6: 4) Each household should be composed of only adults and elders with sibling, married, or parent-child relationship and a maximum of 2 pets. No roommates allowed; you may only combine households in-game. There should only be one married couple and offspring should always have a set of parents. So for example, if you rolled 6, that gives you four Sims. You may have 4 siblings, 3 siblings where one of them is married, 2 elder siblings where one is married and has an adult child, or an elder couple with two adult children. If you rolled 4, you get three Sims. You may have 3 siblings, 2 siblings where one is married, and an elder couple with one adult child. If you rolled 2, you get two Sims. They may be siblings or a couple. And if you rolled 1, he's single. If it's still unclear to you, here's a guide. (SP: Spouse, SI: Sibling, PA: Parent, CH: Child)

You are free to choose your Sims' skin color, hair, clothes, and the rest. However, you're not free to choose their personality and aspirations. To determine their aspirations, roll the dice once. (1: Family, 2: Fortune, 3: Knowledge, 4:l Popularity, 5: Romance, 6: Pleasure) To determine their personalities, roll the dice twice and get the sum. (2: Capricorn, 3: Aquarius, 4: Pisces, 5: Aries, 6: Taurus, 7: Gemini, 8: Cancer, 9: Virgo, 10: Libra, 11: Sagittarius) You may tweak their personality traits as long as it doesn't change the sign assigned to them.

Note that these rules should be applied every time you create a household.

MOVING IN

Your settlers must build their house in an empty lot (beach lots are allowed) of any size. You may use build cheats! You have access to phone, water, and electricity. Unfortunately, fire, burglar alarms and water sprinklers are locked (See Town Expansion, Police Station) and phone services are very limited. (See Unlocking Services) You are not allowed to buy a new fridge after you've purchased your first one. You have to fish or grow your own garden to restock it (See Town Expansion, Grocery). Also, you may only use cars after you've built your town's first community lot. This includes the junk car.

Further in the game you will unlock establishments that will reward you with either a CAS household or a residential lot. (See Town Expansion) Keep in mind that a household will need a residential lot or apartment space to move in. This includes transferring. An available residential lot may be empty or an unoccupied house. A built house cannot be bulldozed but can be renovated. Also, an empty residential lot must remain empty until a family moves in it and build their own house. You may only move your family to a new place if they have lived in their current house for a minimum of 21 Sim days.

UNLOCKING SERVICES

To unlock phone services, your household must have a phone. You may use the phone for social interactions and social services. However, some services require establishments (See Town Expansion) or people to function. The list below shows the locked services.

To grow your town, you must have community lots. And to have community lots, you must find the right Sims who mastered their career to help you. But since you only have your settlers to begin with, you will not find these Sims-- you will make them. Here's the list of careers you can pursue to unlock establishments and expand your town:

Architecture - Open to your settlers and Art and Mathematics graduates only. Only one City Planner (Rank 10) allowed at a time.*

* If another Sim accidentally tops the career, you must roll the dice once to seal their fate. 1-3: The challenger replaces the former Sim and the former Sim must quit immediately. 4-6: The former Sim retains his job and the challenger must quit immediately. Tough luck, so be watchful!

Tip: Make sure you have at least one settler in the Architecture, Education, Law, and Politics career for a quick start.

And that's it! I hope you find these rules fun and challenging! Thanks!

I've got a town for this challenge in TS2UC and I'll be using a Modded game to fix issues and keep community lot visitors under control.I'll modify a few rules as needed though like only allowing part-time jobs for the first settlers.I've got a Mod that unlocks that for adults.

I would not allow sprinklers before you have a fire service. Sprinklers in real life require a lot of plumbing and maintenance (in fact I would only allow them in appartment or community lots), whereas fire men could be represented by your neighbors carrying water buckets.

I'll put it in the rules that sprinklers are required as a proxy for buckets being used to put fires out and firealarms for the green energy sources as the sims need those out out or the fire would spread over their property.I also have minumun numbers of households required for adding subhoods and a requirement for how many shopping districts are to be added before adding a downtown.
I would also use a Mod found here that fixes the subhood selection UI so you won't have to activate the default downtown and shopping districts before selecting custom maps for those.

I've been playing this BACC for a while now and it's going really well! I just unlocked community lots and built a grocery store. I also made a spreadsheet to go along with it and I'll attach a blank version here.

I love this version of the rules. Have I missed something - how do you know when you've "won", is there an ultimate goal? Most of them use a multiplying factor system to get to a "population" of 50K, but this one thankfully does not. Is it just having all the community lots built, uni/downtown/shopping district opened and all careers with at least one sim at level 10? Thanks!

Hi! The only goal here is to enjoy building your city until you're satisfied with it! Hahaha! Glad you like it!
